Exhibit 99.2

Team -

Today we announced the filing of a preliminary proxy statement in connection with our agreement with Sprint and I’d like to provide an update on the pending transaction.

The Clearwire board’s Special Committee will continue to evaluate the proposal from DISH and engage in discussions with both DISH and Sprint, as appropriate. The Special Committee has not made any determination to change its recommendation of the current Sprint transaction.

It is imperative during this process that we focus on executing our daily duties to successfully manage our business, including our wholesale and retail operations and LTE network build. The LTE network remains central to our future plans. We continue to work with Sprint on an accelerated build plan, but we have not yet come to an agreement. We have amended the Sprint Financing Agreements to extend the date by which an agreement on the accelerated build out must be reached to February 28, 2013.

We will continue to update you on any new developments. The leadership team and I also look forward to meeting with you in a few weeks to share our Q4 and Full Year 2012 results, as well as answer any questions. In the meantime let’s continue to kick-off a great first quarter.
